Abstract

Abstract A one-sided corrugated cardboard machine comprising a machine stand with two fluted rollers in meshing engagement with each other and an auxiliary roller rotatably supported therein, the axes of said rollers being disposed approximately in a common plane preferably inclined towards the vertical, with the machine stand being supported at the underground on one side of the plane, and members cooperating with the roller pack such as deviation rollers, guide plates, scrapers for the pressure roller, and the like, being supported in a stand section on the other side of the plane, said section being a rigid frame spanning the roller pack and which is detachably yet fixedly connectible to the machine stand.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 165 words
A one-sided corrugated cardboard machine comprising a machine stand defining an internal cavity and an opening at a portion of said cavity for affording access to said cavity, a roller pack comprised of two fluted rollers in meshing engagement with each other and a pressure roller rotatably supported within said machine stand internal cavity beneath and accessible through said opening, the axess of said rollers being disposed substantially in a common plane beneath said opening, and web processing members cooperating with said roller pack for forming a web into corrugated cardboard supported on the other side of the plane, characterized in that the cooperating web processing members are carried by a rigid frame comprising a pair of spaced apart side members rigidly interconnected by means of at least one transversely extending member spanning said roller pack and detachably connected by means of removable fasteners to said machine stand and extending across said opening and in proximate to said machine frame for reinforcing said machine frame.
Claim 2
Dependent Claim 165 words
A one-sided corrugated cardboard machine comprising a machine stand defining an internal cavity and an opening at a portion of said cavity for affording access to said cavity, a roller pack comprised of two fluted rollers in meshing engagement with each other and a pressure roller rotatably supported within said machine stand internal cavity beneath and accessible through said opening, the axess of said rollers being disposed substantially in a common plane beneath said opening, and web processing members cooperating with said roller pack for forming a web into corrugated cardboard supported on the other side of the plane, characterized in that the cooperating web processing members are carried by a rigid frame comprising a pair of spaced apart side members rigidly interconnected by means of at least one transversely extending member spanning said roller pack and detachably connected by means of removable fasteners to said machine stand and extending across said opening and in proximate to said machine frame for reinforcing said machine frame.
